Ever since the SiteMeter fiasco, I’ve been looking for a blog stat package that I can believe.
Unfortunately I’ve not been successful.
After a few weeks I can positively say, they’re all wrong.
None of them agree with the httpd logs. StatPress and CyStats are the closest to the httpd logs in terms of counting raw hits, but that’s it. They all vary (wildly) in visit counts, top read posts and other metrics.
SiteMeter is so inaccurate I’m not even bothering with it any more. I suspect it’s because many browsers block the scripts that SiteMeter relies on.
I have drawn a few conclusions so far.
1. Any stat service external to the blog will under count hits and visits.
2. Any stat counter that relies on scripts will under count hits and visits.
3. Hit count stats are most likely to agree with the httpd logs. Other metrics depend on the algorithms used by the developer and cannot be used to compare between different stat packages.
